Definitions

• the invention relates to a metal-encapsulated medium-voltage switchgear panel with a switch compartment for a circuit breaker and with a busbar compartment arranged in a rear part of the switch panel and a cable connection compartment, furthermore with a low-voltage compartment arranged above the switch compartment and front doors for the switch compartment and the low-voltage compartment.
• Examples of medium voltage switch fields are e.g. the DE - company publication "Siemens: Medium Voltage Circuit Breaker Program Overview", order no. E 50001-U 229-AI, issued April 1991.
• the busbar compartment, the cable connection compartment and the switch compartment are separated from one another by the partition walls mentioned, while in the case of unshielded or partially partitioned panels, the spaces mentioned are to be regarded as a functional subdivision of an overall space.
• the different embodiments of the shift sensors mentioned are selected on the basis of the respective requirements.
• the particularly high level of safety when the interior is subdivided by sheet steel partition walls is offset by the lower depth and thus the smaller space requirement for switchgear panels with an unsealed or partially partitioned design. Since it has been found in practice that both types of panels are used, it is accordingly necessary to manufacture both Tools and devices required for construction methods. This leads to a not inconsiderable effort.
• the object of the invention is to simplify the optional manufacture of both types of medium-voltage switchgear panels and thus to reduce the outlay.
• the cable connection space and the busbar space are contained in a first housing body which is open to the front, a front frame for holding the door arrangement of the switch space and at least part of the switch space is part of a second housing body which is open to the rear are and the first and the second housing body have the same width and interconnectable frame parts.
• the scaffold for a cubicle of the unshielded design is now produced by connecting a first and a second housing body directly to one another.
• the same housing bodies can also be used for a cubicle of the bulkhead construction if, according to an embodiment of the invention, a third housing body is inserted between the first and the second housing body, the depth of which roughly corresponds to the space required for the switch space of the bulkhead separating the cable connection space and the busbar space and accommodating the separating contact bushings is dimensioned. Only this third housing body, that is to say a part of a relatively small volume, is to be produced in order to be able to produce a cubicle with a poured construction using the already existing first and second housing bodies.
• the second housing body be fitted on its rear side with a connecting frame that can be attached to the first or third housing body. Furthermore, it is advantageous for the assembly of the housing bodies if the first housing body has a base plate with profiled bevels at the edges, part of the base plate projecting beyond a front frame and the second housing body being attachable to the projecting portion of the base plate and is connectable to the section.
• the third housing body can also be easily aligned with the other housing bodies in that, according to a further embodiment of the invention, the third housing body has a base plate with profiled bevels on the edge and that a portal mounted on the base plate places the base plate in a rear Section and a front section divided, the front section corresponds in length and shape to the section of the bottom plate of the first housing body.
• Protective work plates have been developed for the safe handling of switchboards of the unsealed construction, which temporarily separate the busbar area from the switch room.
• Such work protection plates can also be used in control panels according to the present invention if the front frame of the second housing body has a slot-like passage opening arranged above the door opening for introducing a work protection plate.
• FIG. 1 shows a medium-voltage control panel of the unscottled construction in a side view with the cover removed.
• FIG. 2 shows a cubicle of the partitioned construction.
• FIG. 3 shows a perspective and exploded view of a first housing body and a second housing body for forming a switch panel of the unsealed design.
• FIG. 3 The same housing body as in FIG. 3 and additionally a third housing body to be inserted between them are shown in FIG. This arrangement is used to build a cubicle of the bulkhead construction.
• FIGS. 1 and 2 serve only to illustrate known device configurations in unshielded and bulkheaded medium-voltage switchgear and the resulting different space requirements of the panels.
• the structure of the housing of such panels according to the invention is subsequently explained with reference to FIGS.
• the control panel 1 according to FIG. 1 has a switch space 2, in which a vacuum circuit breaker 3 is shown as an example of a switching device.
• a busbar compartment 4 with busbars 5.
• Disconnect contact arrangements allow the circuit breaker 3 to be moved from the operating position shown with the door 7 closed to a disconnected position.
• the lower rear area of the control panel 1 there is a cable connection space 10 into which cables 11 are inserted from below.
• the components mentioned with reference to FIG. 1 are also contained in the control panel 20 according to FIG. 2 and are provided with the same reference numerals there, but the switch compartment 2, the busbar compartment 4 and the cable connection compartment 10 are separated from one another by bulkhead walls.
• a bulkhead 21 extending over the entire height of the control panel 20 and a further bulkhead 22 separating the busbar space from the cable connection space 10 are provided.
• upper bushings 23 and lower bushings 24 are inserted into the bulkhead wall 21.
• the bulkheads 21 and 22 ensure that an arcing fault occurring in one of rooms 2, 4 and 10 remains restricted to the room in question and the other rooms are not impaired.
• the construction with bulkhead walls requires a greater depth of the control panel 20 than the control panel 1 in FIG. 1.
• a control panel of the unshielded construction is to be accommodated approximately in accordance with FIG. 1 in a housing 30 which can be assembled from a first housing body 31 and a second housing body 32.
• the housing bodies 31 and 32 are shown pulled apart, the overall dimensions being illustrated by dash-dotted lines, however, to illustrate the overall dimensions following the housing body 31.
• the housing body 31 consists partly of solid wall parts and partly from scaffolding or frame elements. These parts form two side frames 33 and a front frame 34, over which a base plate 35 projects forward with a section 36.
• the base plate 35 has profiled bends 37.
• the second housing body 32 has a front frame 38 for a door arrangement and an insertion slot 40 above for a work protection plate.
• the housing body 32 has the same height as the housing body 31 and has such a depth that in the assembled state, as indicated by dash-dotted lines in FIG. 3 following the housing body 31, results in the volume required for an unshielded switch panel .
• the profiled bevels 37 protruding from the front frame 34 facilitate the accurate assembly of the two housing bodies 31 and 32 in that a corresponding recess 41 is provided on the sides of the second housing body 32. This extends up to the rear of the front frame 38.
• the housing bodies 31 and 32 can be connected in such a way that, after the second housing body 32 has been placed on the folds 37, the front frame 34 of the housing body 31 is aligned with one another with a rear frame 42 of the housing body 32 and with a number of screws is connected or continuously or locally welded.
• FIG. 4 shows a third housing body 45, which has the same height and width as the housing bodies 31 and 32.
• the housing body 45 consists of a base plate 46 with profiled bends 47, the shape of which corresponds to the bends 36 of the housing body 31.
• the portal 50 divides the base plate 46 into a shorter rear section 51 and a longer section 52, the longer section 52 being the Section 36 of the housing body 31 corresponds.
• the rear section 51 is dimensioned such that, together with the section 36, the distance between the first housing body 31 and the second housing body 32 results, which is required for a partitioned switching field according to FIG. 2.
• a roof plate 53 and side walls 54 of the third housing body 45 are to be connected to the first housing body 31.
• the front of the portal 50 corresponds to the front frame 34 of the first housing body 31, so that the connection of the second housing body 32 can take place in the same way as in the example according to FIG. 3.
• a bulkhead with bushings for isolating contacts can be inserted between the first housing body 31 and the third housing body 45, for example as a scaffold-high component.
